Specification of Letters Patent.

Patented Mar. 20, 1917.

Application filed October 21, 1914. Serial No. 867,870.

To all whom it may concern Be it known that I, J AMES IV. a citizen of the United States, Lookeba, in the county of Caddo and State of Oklahoma, have invented a new and useful Improvement in Cotton-Pickers, of which the following is a specification.

This invention is animprovement upon the collector or cotton picking device employed in connection with the cotton picking device shown in the patent granted to me Dec. 9, 1913, and bearing the number 1,080,899.

The object of the invention is to improve the specific construction of the cotton extricating devices, and also to enable the operator to handle the nozzle more quickly by improving the means for connecting the cotton extricating devices to the main suction apparatus.

With these objects in view the invention consists of the novel features of construction hereinafter described, pointed out in the claims and shown in the accompanying drawings, in which:

Figure 1 is a side elevation of my nozzle connected to a suitable suction pipe.

Fig. 2 is a front end view.

Fig. 3 is an inverted plan View of the forward portion of the nozzle.

Fig. 4 is a longitudinal section taken vertically through the nozzle.

Fig. 5 is a plan view partly in section illustrating the improved method of connecting the nozzle shown in the previous views so that the same can be swung freely to reach the bolls.

Fig. 6 is a side elevation of Fig. 5.

As shown in the patent referred to suitable suction creating means are provided together .with suitable means for conveying from the collector the cotton extricated from the bolls, said means delivering the cotton at a suitable point. Also as illustrated in said application the same source DINSMORE,

of motive power was employed for the purpose of operating the suctioncreating devices as for driving the mechanism carried by the nozzle.

In the drawings forming a part of this application 1 represents a conveyer pipe and 2 a suitable belt for driving the mechanism carried by the nozzle and to be hereafter described. The pipe 1 and belt 2 are both fully shown and described in my previous application.

residing at Secured by any desired means to the pipe 1 a cotton receiving casing 3 provided at its rear end with a transverse shaft 1, which shaft carries upon the outer side of the easing a pulley 5 over which runs the belt and within the casing a grooved drum 6. In the forward portion of the casing is arranged a suitable shaft 8, upon which rotates a cylindrical screen 9. In my previous device this screen was driven by means exterior to the casing.

In my present construction I employ an interior drive mechanism and also make use of the same mechanism for positively carrying the cotton through the casing 3 and into the suction tube. This means consists of a belt 10 which runs over the drum 6 midway its ends and over the screen 9, and the said belt carries upon its outer face inclined projecting prongs 11, said prongs projecting downwardly and rearwardly during their period of travel from the screen 9 to the drum 6, and positively carrying the cotton along the lower portion of the casing. As shown in Fig. 2 the belt 10 is comparatively narrow so that .it offers a very slight obstruction to the entrance of cotton fibers into the casing and to the free passage of air currents through the screen 9.

To further cooperate with the screen and the prongs 11 to insure removal of the cot ton from the boll and its passage into the suction devices I mount upon opposite sides of the casing 3 suitable pivoted arms 13 which project in advance of the casing and upon the forward free ends of which are mounted suitable toothed disks 11 and 15, said disks having hub portions over which run belts 16, said belts running over the grooved portions of the drum 6, said belts being placed respectively upon opposite sides of the belt 10. One of these arms is provided with a suitable spring 17 so asto hold the disk 15 close to the screen 9, the spring allowing suflicient yielding movement to permit passage of the cotton. Both arms may be provided with springs if desired.

It will be noted from Fig. 4 that as the belt 10 passes over the roller these teeth 11 point in such a direction that the air suction through the casing 3 will clean them of cotton before reaching the top of the drum.

lYhile the nozzle above described may be used with advantage in connection with the apparatus shown in my allowed application ''shaft 4. A central above mentioned in order that it may have a freer movement thereby enabling access to e had to all of'the bolls I prefer to connect the casing 3 to the suction pipe 1 by means of a universal joint. In Fig. 5 I have shown the casing 3 connected directly to a flexible hosesection 18 which in turn will lead to the pipe 1. Mounted upon any suitable fixed support 19 is a bar 20 provided with a socket 21 in which turns a ball 22, said ball being provided with a rod 23 connected to one end of a frame 24. The bottom end of the frame 2-1 carries a shaft 25 which passes through the casing 3 and corresponds with the shaft 4 previously described, said shaft is provided with pulleys 26 which correspond to the pulley- 5, and it will of course be understood that the pulley 5 can be duplicated in the construction shown in Fig. 1 if desired, that is, the pulley 5 can be placed upon the end portions of the shaft 27 carried by the frame 21 carries at its ends pulleys 28 and within the frame a larger pulley 29. Belts 2 run over the pulleys 26 and 28. From the drive pulley 30 suitably mounted upon a rotatable shaft 31 carried by any convenient fixed support and driven in any desired manner runs a belt 32 and said belt is'passed around the ball and socket joint by means of idlers 33 carried by bracket arms Ellwhich are connectedv to a suitable sleeve 35 in turn mounted upon the rod 23. By means of this construction the casing 3 and the mechanism carried therein can be swung in any direction without interferin; with the means disks for driving the various parts of the picking mechanism.

Byhaving the belts 16 pressed tight against the toothed portions of the disks 1 1 and 15 the said belts will serve to keep these toothed disks clean of any cotton Which might otherwise'tend to stick to them and clog the teeth.

Openings 16 are formed in the bottom of the casing 1 through which the belt 16 travels.

What I claim is 1. The combination with a suction pipe,

a IIOZZIeKmQYBbIe freely in any plane, a rotatable screenmounted at the forward end of the nozzle,

a narrow belt traveling over said screen and rotating the same, prongs carried by said belt, boll engaging toothed supported from the forward end of the nozzles, and means for causing said disks to rotate in a direction reverse to the rotation of the .screen.

2. A device of the kind described comprising a nozzle, a rotatable screen in the forward end of the nozzle, a rotatable drum in the rear end of the nozzle, a belt running over said belt and screen, prongs carried by the belt, pivoted arms carried by the sides of the nozzle, toothed disks carried by the said arms and crossed belts running respectively from said drum to said disks in a direction reverse .to the rotation of the screen.
